On the contrary, I would recommend Samba 3 with Samba 3 winbindd as domain 
member for the setup you describe. If I understand you correctly, you need the 
linux machine to authenticate users against the AD domain, possibly for other 
services running on the linux box like Squid, Radius or whatever else. In my 
opinion Samba 4 winbind is not up to the job yet, and Samba 4 can't use the 
Samba 3 winbindd either. So assuming you don't need the linux box to be 
another domain controller, Samba 3 should be able to handle the job just fine.

Actually this bug is about S4 failing to provide the information S3 member 
servers expect to receive via winbind. This has nothing to do with using the 
S3 winbindd while actually running Samba 4, which also fails but for entirely 
different reasons.
